+reset-master – The master was reset. +slave – A new slave was detected and attached. +failover-state-reconf-slaves – Failover state changed to reconf-slaves state. +failover-detected – A failover started by another Sentinel or any other external entity was detected (An attached slave turned into a master). +slave-reconf-sent – The leader sentinel sent the SLAVEOF command to this instance in order to reconfigure it for the new slave. +slave-reconf-inprog – The slave being reconfigured showed to be a slave of the new master ip:port pair, but the synchronization process is not yet complete. +slave-reconf-done – The slave is now synchronized with the new master. -dup-sentinel – One or more sentinels for the specified master were removed as duplicated (this happens for instance when a Sentinel instance is restarted). +sentinel – A new sentinel for this master was detected and attached. +sdown – The specified instance is now in Subjectively Down state. -sdown – The specified instance is no longer in Subjectively Down state. +odown – The specified instance is now in Objectively Down state. -odown – The specified instance is no longer in Objectively Down state. +new-epoch – The current epoch was updated. +try-failover – New failover in progress, waiting to be elected by the majority. +elected-leader – Won the election for the specified epoch, can do the failover. +failover-state-select-slave – New failover state is select-slave: we are trying to find a suitable slave for promotion. no-good-slave – There is no good slave to promote. Currently we’ll try after some time, but probably this will change and the state machine will abort the failover at all in this case. selected-slave – We found the specified good slave to promote. failover-state-send-slaveof-noone – We are trying to reconfigure the promoted slave as master, waiting for it to switch. failover-end-for-timeout – The failover terminated for timeout, slaves will eventually be configured to replicate with the new master anyway. failover-end – The failover terminated with success. All the slaves appears to be reconfigured to replicate with the new master. switch-master – The master new IP and address is the specified one after a configuration change. This is the message most external users are interested in. +tilt – Tilt mode entered. -tilt – Tilt mode exited.
